efuse中的margin read efuse是一种电子器件，常用于存储和控制芯片的一些重要参数和配置信息。marginread是efuse的一种读取模式，用于验证efuse中存储的数据的正确性和可靠性。在efuse中，marginread是一种高精度的读取模式，它通过在读取时加入一定的电压偏置，在边缘情况下读取efuse的数据。这种读取方式可以检测e...
Hello, I found it weird that the get property is working properly, but the read fuse not. Are you trying to read the same fuse in the EVK and your

An eFuse reference cell on a chip provides a reference voltage that is greater than a maximum voltage produced by an eFuse cell having an unblown eFuse on the chip but less than a minimum voltage produced by an eFuse cell having a blown eFuse on the chip. A reference current flows ...
My program generates a unique ID using rnd and timestamp when it is first turned on. I want to save it in Efuse BLOCK3-Variable Block 3. I'm afraid of experiments with EFUSE and so I want to ask how to do it. 1. How can I write EFUSE BLK3 from a user application?
Do the syscalls to blow an eFuse do something different than just writing to the sFlash? Also is the sFlash then OTP?READING THE EFUSES:Is reading the addresses still possible even after blowing the eFuses? I tried with the code example provided in the reference manual and I run i...
在此表中,它表示默认为eFuse定义的值。 这是TI设置的双核还是单核模式功能? 客户是否需要设置eFuse? 他们的系统中没有任何OTP,因此他们希望避免使用eFuse。 如果有任何参考资料,也将不胜感激。 此致, Mari 请注意,本文内容源自机器翻译,可能存在语法或其它翻译错误,仅供参考。...
The efuse memory cell has a write bit line terminal, a read bit line terminal, a read word line terminal, and a write word line terminal. The efuse memory cell further includes: an electric fuse, having a first terminal connecting to the write bit line terminal and a second terminal; ...
